The question you're asking about what if there are more than one perfect brackets is answered like so: The $1 billion is divided among those winners. If there is one winner, you can elect to receive the billion over 40 annual payments of $25 million, or one lump sum of $500 million. Doesn't sound like a bad deal either way.

The billion isn't just coming from Gilbert and Quicken's coffers, but also from Berkshire Hathaway and Warren Buffett, who you might remember made a big hubbub about saving Detroit through small businesses or some shit when he visited town a few weeks ago.

Quicken is also donating a hefty $1 million to inner-city kids in Detroit and Cleveland. So if you're stuck in a cycle of poverty, you have to share $1 million between thousands of other kids between two cities. But if you're lucky at basketball, you get a billion. Good to know!

The full rules of the contest where a billion dollars is at stake hasn't been released yet, but you can read more about the contest here. Good luck!
